Southern California weather to warm up this week

Today will be a relatively cold day across most of Southern California, but forecasters expect the weather to remain sunny and get warmer during the week.

Although National Weather Service forecasters expect warming temperatures across the region, the possibility of frost remains in some inland areas. Overnight temperatures may drop to or below freezing around the San Gabriel Valley and Inland Empire, creating the possibility of a frost that may harm outdoor plants if left uncovered.

Daytime temperatures in the Los Angeles and San Gabriel Valley areas are expected to be in the 50s today. Conditions will be colder in the Inland Empire, where temperatures may get no warmer than the high 40s.

Residents across Southern California can look forward to temperatures rising to the low 70s by Thursday, the National Weather Service reports.
